3.2.3;Swing app.; Cannot work with two applications at the same time.

Hi guys,
I bring this problem here may somebody experienced that.
I developed two client side applications(applets) with JDev3.2.3.
Locate them on Apache/Tomcat. There is also a
Index.html file with two links, so when user clicks on
each link the associated application will downloaded
on his/her PC and ready to work. (In index.html I used
JavaScript function window.open(…) to load the applications)
Now please see this scenario:
1-I ran/loaded both application in two separate
browsers(IE5.5). And tried to work with them(minimized
one and work with another). Soon I faced unexpected
frizzing/locking or very slow running on both
applications.
2-Then closed/killed one of them(killed IE). Then
re-executed same application again. The application
loaded with the last activated screen . Seems it never
killed and it was still alive.
3- The only way to successfully working is one by one.
Means execute & work with one, then kill that, and
then execute and work with another. Which is not expected
in the Windows enviroment.
To Debug:
When both applications were running(each on it’s own
IE), I opened the Task Manager and saw there was only
one IEXPLORER.EXE was running, also there was only one
Java VM (a little bird icon) on right-bottom of the
screen.
I believe this causes the problem. Seems they both
running in the same session. Since I opened two
applications in two IE I was expected to see two
IEXPLORER.EXE with two JVM. Am I right? Do you think
so?
Any way, Now I am seeking to find the solution. My
primary mind says probably I should not use
window.open(..) in index.html to load the
applications.
Would appreciate any command on this.

Same thing with me! My microphone doesn't even register in anything but ventrilo!
It's dri'ves me NUTS! I bought the card (xfi fatalty) for a really good price, but I almost regret even looking into the soundcard because of this bug. I know Vista is a new operating system..but I figure'd this kind of update should have been noticed MUCH earlier..
Please creative, can you fix this?
On another note..is there a sound quality difference between using an x-fi in vista vs xp?
*not meaning to thread jack*
finally..
you should probably close the other thread.. You made two, you know.

Apex mixes applications working with two windows at the same time

Hi all, while developing in Apex I have found the following problem:
Working with two different applications at the same time, the browser goes from one to another indistinctly.
To reproduce the problem:
1. Open the same application builder in two different Firefox windows
2. Open a different application in each window (In my case: application 103 in window1 and application 105 in window2)
3. Go to shared components in both windows (window1 first)
- window1 breadcrumbs show: Home > Application Builder > Application 103 > Shared Components
- window2 breadcrumbs show: Home > Application Builder > Application 105 > Shared Components
4. Click in any shared component in window1 (Templates, Authentication Schemes...)
- window1 breadcrumbs show: Home > Application Builder > Application *105* > Shared Components > Templates (Application 105 instead of 103)
Is it a bug? I have read the known issues [[Here]|http://www.oracle.com/technetwork/developer-tools/apex/downloads/apex402knownissues-189793.html] but it does not appear.
Related Data:
Application Express version 4.0.2.00.07
Firefox 3.6.15
SO: Windows XP
The error is not reproduced with IE7. I have not tested any other browser.

If you tried opening up two pages in the same application each of which modifies the same page items, you would notice the same issue.
This is because, in a session there is only one set of values for page items(or application items) and every parallel call to the same page would update the same bind variables.
Now the development environment or Apex Builder is also an apex application , and when try and open up the pages as you mentioned, they both access the same Application Builder page and sets/resets any existing values for those variables(and maybe cookies too if they are being used) , hence the 'mixing up'.
If that didn't convince you, check the URL of both the pages when you load them, they should show the same page number ( f?p=APP_ID:PAGE_NUMBER syntax). Imagine if the same approach was done with one of your application pages, say an edit form opened from a report with multiple records in multiple tabs like what happened with this case: {message:id=9346663}
So this really isn't a bug in a way, because that is how session states in apex is/was maintained. Ofcourse if they used another kind of development platform for building pages, it may have been avoided, but thats an altogether different point in itself.

How can I work with two images at the same time?

I have downloaded Photoshop Elements 10 and I can not find the buttons for Minimize or Reset for the image. If I rightclick the miniature those options are grey. If I open two images so I have two miniatures in the holder and then go to Windows and Images the option Show Overlapping is grey but I can show Side by side. Then I can only shut down the images.
Thanks for help

Using a Dell 2407WFP with two Macs at the same time?

Hi ... I have a Dell Ultrasharp 24" WFP display that I was using with my old G4. Connectivity isn't the issue ... it works beautifully on both the G4 and my new Mini. I've read that I can put the VGA cable on the G4 (no biggie -- it's what I was using before) and I have the DVI on the Mini.
What I want to know is: Can I (and is it wise to) have both machines running at the same time and toggle the display between the two or should I keep one machine off when the other is on? There is a button on the display for toggling between a variety of displays.
I've activated file sharing, etc. on the old box, but there are some things I still can't do unless I'm on the G4 desktop -- mostly my graphic apps. I've been holding off from swapping cables around, but now it's getting to the point that I need to get back on the G4 because of apps that I don't have on the Mini.
I haven't put the VGA cable back on the G4 yet. It seems like it -should- work -- I just need some verification that it will or won't futz up something. I think what I might be most concerned about is that the monitor isn't powerful enough to run both machines at the same time, but I could be wrong.
The info at the Dell site is somewhat dated.
TIA!

I use a KVM switch with a Dell monitor that has DVI and VGA inputs. I only route the K an M portions (keyboard and mouse) through the switch. The computers connect directly via VGA and DVI to the Monitor, and then I use the monitor's switch to make the video switch. Works fine. Don't worry about taxing the monitor.
I'd suggest buying the KVM switch from a vendor with easy return policies, since it can take a few tries to find a model you like.

The app Spaces keeps me from using two applications at the same time.

I set up Spaces but now experience a bad side-effect. When I need to have Two files/folders/whatever in use because I want to place something from X into Y, I cannot do it because Spaces only lets One application on the desktop at the time; it shoos all the other applications away, and in doing so, it takes away the thing that I wanted to place into the new application that swooshed onto my desktop when I pressed its corresponding square in the Spaces icon in the top control panel.
How can I arrange it so that I can keep Two or three applications available for me to do transfers from one to another?
~ Lorna in Southern California

Ferrell, I have done what you suggested. I clicked onto the Spaces icon in the upper control panel and assigned spaces to six apps: Mail, Safari, iPhoto, iMovie, Pages, and iWeb.
The problem is that if I am one app and I want to put something into that app, then the minute my mouse cursor goes to get that other thing, the original application into which I want the thing put GETS WHOOSHED OFF THE DESKTOP. What I want is for the original app to remain open whilst I go to retrieve a file or folder, and stay open while I put that thing into the original app.
How does one turn off Spaces? I don't mean to delete all the names from the settings.I mean, just turn it off for a while so I can do something which requires for two apps to be open at the same time????

Can I use one GBIP-Interface with two programs at the same time?

Hi, I have one PCI-GBIP-controller with multiple instruments installed. Now I want to use these instruments with two differents programs at the same time.
E.g.: program 1 uses GPIB0::1 and GPIB0::3
and program 2 uses GPIB0::4 and GPIB0::7
Is this possible??
When I have tried to do this, I always got timeout errors..
Thanx in advance.
Philipp

Hi,
You shouldn't have any problems accessing different devices from different programs using the same interface. I even used the two VIs to communicate with the same device. Although not the best approach, VISA didn't return any errors.

[CS3 JS] Working with two documents of the same name

I work with sets of documents that use standardized names. I'm trying to write a script that compares two documents from different sets. Because the source and the target documents both have the same name, I've encountered some disturbing behavior that reminds me of the app.activeWindow bug that Dave has written about. (
Dave Saunders, "Scripting FAQ as Wiki" #14, 15 Oct 2007 12:19 pm)
To perform the comparison, I have to grab a reference to the same region of text in both documents, as offset from regular landmarks. I was just patting myself on the back for figuring out the "story.characters.itemByRange(begin, end).texts[0]" acrobatics required, when I discovered that my text objects were magically "dissolving" into invalid objects.
After a lot of debugging and attempts to hack around the problem (i.e. storing the text begin/end indices and not grabbing the text object until the last possible moment), I've narrowed it down to the references to the source and target documents. I've watched the reference variable to the source document *change* to instead reference the target document when I start accessing the target document object. Once this happens, any text objects belonging to the source document become invalid, as if the source document had been closed.
Is there any way around this? I've thought about temporarily saving the files to different names, but I haven't tried it yet.
Here's a script that demonstrates the problem (you'll have to find your own same-named documents if you want to run it):
var source = "/Users/deyk/Desktop/test/source";
var target = "/Users/deyk/Desktop/test/target";
function findChapters(in_doc) {
app.findGrepPreferences = NothingEnum.nothing;
app.findGrepPreferences.appliedCharacterStyle = "chapter-num";
app.findGrepPreferences.findWhat = "\\d+";
return in_doc.findGrep();
var sdoc = app.open(File(source+"/01.Genesis.indd"));
var s_file_start = sdoc.fullName;
var s_chs = findChapters(sdoc);
var s_story = s_chs[0].parentStory;
var s_txt = s_story.characters.itemByRange(s_chs[0].index,
s_chs[1].index-1).texts[0];
var tdoc = app.open(File(target+"/01.Genesis.indd"));
// At this point, sdoc now references tdoc instead.
// s_txt, s_story, and s_chs become invalid objects.
var t_file_start = tdoc.fullName;
var t_chs = findChapters(tdoc);
var t_story = t_chs[0].parentStory;
var t_txt = t_story.characters.itemByRange(t_chs[0].index,
t_chs[1].index-1).texts[0];
var s_file_end = sdoc.fullName;
if (s_file_end.name != s_file_start.name) {
var result = "What a nasty bug!";
"Finished";

I've tried saving the document to a temporary name, and it works satisfactorily:
function openFileAsTemp(a_file) {
var tmp_folder = Folder.temp.fullName;
var date = new Date();
var temp_file = File(tmp_folder+'/'+date.valueOf()+'_'+a_file.name);
var doc = app.open(a_file);
doc = doc.save(temp_file);
return doc;

Working with mutiple windows at the same time

I'm using a rtm which selects various vi's, I want each of the vi's to up-date with data all the time as they are selected. The problem is that, as each one is selected the others stop receiving data. I have to highlight each one again I have tried to use Globals but this isn't working to well. Any idea's with examples would be handy

If you call the VIs statically in the same loop when they are selected then data flow will prevent anything from happening until the one already running has stopped.
If you want them to run in parallell you'll have to call them so that they do not stop the data flow from calling the others...that means calling them in separate loops or dynamically using an invoke node with the wait until finished flag set to false.

Working on two imovies at the same time

Using mainstage with two instruments at the same time

Hi, I'm using an M-Audio firewire solo as an interface with my macbook. I have a usb keyboard and want to play guitar as well, switching between the two onstage. My question is, how do I get the outputs to the soundboard so they can be mixed separately? The interface has two inputs and balanced outputs (ch1 and ch2). I want channel 1 (gtr) to go to ch1 of the output and channel 2 (keys) to go to ch2 of the output so they can be mixed to the front of house and monitor mixes. Is this even possible using mainstage or logic, or even by just using the headphone out on the macbook?

Since MainStage only deals with outputs in stereo. You'll need to do some panning. Pan your Guitar fully LEFT, and your keys fully RIGHT. That'll give you two separate outputs....
FYI, there are some issues with panning in MainStage 2. So, to get around this.... Create two Sub Aux channels. One called Guitar Out, and the other Keys Out. Do your panning there and not on the individual channels. And send channel one to the Guitar Out Aux, and the Keys to Keys Out Aux.

I purchased Adobe photoshop elements II and Adobe premiere elements II. They are both on one disc. My computer crasded and I had to reload Windows. I only have one serial number and it only works with photoshop II. The same serial number will not work for

I purchased Adobe photoshop elements II and Adobe premiere elements II. They are both on one disc. My computer crasded and I had to reload Windows. I only have one serial number and it only works with photoshop II. The same serial number will not work for Premiere. I dont have any other serial numbers. What do I do???

Static_Unit
I am getting a bit concerned about what is happening in your situation. Yesterday you posted your question in at least two different forums, one of them being here in the Premiere Elements Forum.
Don't Have Serial Number for Premiere, Only Photoshop?
Wherever you posted, the reply was to contact Adobe via its Adobe Chat. It is the only one who can sort out this matter for you.
In the thread cited above I offered to help you with the difficulties that you were having visualizing the Adobe Chat in its web page. I was waiting for your follow up on that in the above thread. Instead, I find your same question in a new Adobe Premiere Elements Forum thread this afternoon with no refer the prior threads or prior recommendations given you.
I will also mention again...when you buy the Photoshop Elements and Premiere Elements bundled in one packaging and with installation files for each on the same installation disc, each program has its own serial number. The Photoshop Elements serial number does not work for Premiere Elements and vice versa. The serial numbers are on labels on a box which houses the installation disc envelope(s). So, if you purchased both programs and found the Photoshop Elements serial number, then the Premiere Elements serial number should be in a label right underneath the label with the serial number for Photoshop Elements. I recall writing this in your yesterday's thread on this matter.
The moderator will no doubt be along shortly to close or delete this thread. So, just in case, please bookmark your yesterday's thread cited above so that we can continue this communication which is trying to help you.
Thanks.

Lightroom CC issues with multiple export at the same time

Back before Lightroom updated to the CC version, I was able to use export presets to send 4 different versions of the photos I'm working on at the same time (A Full Size for client at certain size, full size for myself, web-sized with watermark and a thumbnail). Since updating to the CC version, I'm only able to start the export process on two of these versions before the system simply becomes crippled and I cannot even navigate through Lightroom without it chugging along.
For reference, I'm running a 2014 rMBP with 16GB of RAM, LR is the only app open at the time and it's showing that I have roughly 6GB of RAM free when attempting this export.
TL;DR: LR5 worked wiht multiple exports at the same time, but LRCC now chugs after 2 exports are started

Re: "Selecting video in Messages, now starts Face time for video. Face time is one to one only."
Apple "Messages" supports two different types of video conferencing. It's become more than a little confusing. If you (or the person on the other end) ONLY have accounts set up for Apple's "iMessage" service (associated with your Apple ID and "iCloud") you may see the video symbol, but when you click on it you will be connected via FaceTime which is limited a 1-to-1 video conference.
However, if you have set up an AIM account in Messages (you may already have an AIM account ID if you once used iChat for video, audio and screensharing) and the person at the other end also has an AIM account you will be connected via AIM and will be able to do screen sharing and multi-person video conferences just like the old iChat, i.e. you'll have iChat Theater features, up to 4-way conferencing, etc.
It can get very confusing if, for example, you've signed up for AIM using a .me or .cloud email address. But once you have it set up and learn to recognise the way Messages switches between AIM and iMessage all the old iChat features work just fine in Messages.

Cannot open two pictures at the same time - computer crashes

I have PSE7 and Windows7. I cannot open two pictures at the same time. When I go to open the second picture it crashes PSE7. Anyone know how I can open two pictures at the same time? What is the fix?

Hello Shawbrah
Thanks for your reply.
Yes, your method is actually the only workaround for a workplace with PSE7, but it isn't a solution for our enterprise network/domain.
There are different problems:
We have several computers with PSE7 installed. It does not make sense to manually install a local TCP/IP-printer on each PC.
We have many fluctuation in our company which means that the workplaces will often be moved and the PCs will often be replaced.
If the employees are printing over a local printer, our centralized printer monitor solution does not recognise print volumes.
The printers which are defined on our print server have special tray settings and these settings are "linked" to the core business application. Users should not be able to print with other settings, this could end in a chaos.
Finally to work with PSE in our company, there is no other way than upgrade to PSE8...

HT3529 will imessaging work on two iphones using the same apple id

will imessaging work on two iphones using the same apple id

It will. If the two phones are used by two different people, however, you will need to implement some careful management of your iMessage settings to ensure that you don't each receive each-other's messages. It is a much safer option to use different Apple IDs for each individual.
On iOS devices, you are able to use separate Apple IDs for iMessage and Facetime, iCloud, and the iTunes and App Stores.
